🔌 DENSO SC20HR11 Iridium LONG LIFE Spark Plug - Set of 4 NEW, #3444 Review

These are genuine Toyota Prius and Lexus CT200h spark plugs. They have the same engine. The distance is preset and the fit is perfect. Don't forget to add some anti-seize thread grease and dielectric grease for the coil packs.

Replaced spark plugs showing normal wear with 95,000 new plugs. The spark plug gap does not need to be adjusted. I am very satisfied with the product, the speed of delivery and the results.

My owner's manual says to change the spark plugs every 100,000 miles! Yeah, better than the good old days where it was done every month or so. These spark plugs are recommended by Toyota for my car. And will last another 100,000 miles although I plan on changing them again about halfway through this run.

Do not buy! They have a tip not made of iridium but of copper. Iridium are bluish in color/tint, they have a copper-yellow tip. Made in China. Not sure how Revain can satisfy those fake spark plugs! I finally found the originals at Walmart. The 2010-2015 Toyota Prius needs this specific part number SC20HR11 and not the new part they replaced with SC16HR11 as the new spark plugs are hotter and will not work well in the Prius.

My 2011 Toyota Prius has driven 120,000 miles and had to replace the first spark plug. I followed an online video on You Tube on how to do this and it was pretty easy, it just took time, about 1 1/2 hours. The candles I took out still looked in very good condition. This is a great long lasting spark plug and the car was still running great with the original spark plugs after 120,000 miles.
